MACHINE FOR CUTTING UP GREEN BONES, VEGETABLES, 82c.

Specification of Letters Patent.

Application filed September 9, 1913. Serial N 0. 788,823.

uprovements in Machines for Cutting Up Green Bones, Vegetables, &c., of which the following is a specification.

This invention relates more particularly to that type of machines having a hopper to receive the bones or other material and reciprocating blades in the slidable bottom of said hopper.

The objects of the invention are to provide'an improved drive for the reciprocating plate carrying the cutters, wherebythe pressure exerted within the hopper will not affect the ease of operation of said drive; to provide, an improved and adjustable arrangement of blades or cutters whereby their 1 'manipulation is rendered most efficient; to

provide improved means for exerting pres sure upon the uncut contents of the hopper r to provide such a means which is readily removed, appliedand adjusted; tosecure sim- Z .plicity of construction and operation, and to obtain other advantages and results asmay be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate .the same parts throughout the several views,

Figure 1 is a side elevation of the device, the reciprocating plate carrying the cutters being shown at theextreme end of its stroke away from the operator ,Fig. 2 is a rear ele- '..vation of the samegFig. 3 is a plan of the same; Fig.4 is a section online AFA of Fig. 2, looking in the direction indicated by the arrows; Fig. 5 is a perspective view of the reciprocating blade-carrying plate, and Fig. 6 is a section on line B-B of Fig. 2. I

In the specific embodiment of the'invention illustrated in the said drawings, 1,1 indicatea pair of legs or supports in spaced and parallel relation. Secured to the tops thereofin any suitable manner, as by screws 2 in the laterally open slots 3, is a bridge 4 preferably formed integral with an upwardly extending hopper 5, said hopper being without top or bottom except as hereinafterspecified; I l c of the bottom to said hopperjand immediately below said bridge 4:, is a slidable or reciprocating plate 6 having preferably formed'integral therewith, near its longitudinal edges, racks 7, 7

' A pair of segmental gears 8 to engage said racks to reciprocate the'plate 6 are mounted upon a transverse shaft 10 j ournaled in suitable bearings 11, 11 in the legs '1, 1. In

order to prevent any tendency of the legs to spread, I provide lugs 12, 12 on the shaft adapted in assembling to pass through upward extensions 18 of the hearings in the legs 1, l as shown in Fig. 1, so that one lug as shown. One end of the shaft 10 extends outside the leg thereat and is preferably squared to receive an operating lever or handle 14: held thereon by a pin-15 or other suitable means. It will be evident, therefore, that by swinging thehandle 15 back and forth a resulting reciprocatory movement of the plate 6 is obtained. j A pairof opposed blades or cutters 16, 17 project jinclinedly upward toward each other through saidplate 6 with cutting edges extending transversely of the plate and sewrated one fromthe other at their cutting edges by only a narrow strip of the plate 6. Each of said blades is furthermore longitudinally divided into halves or secwith a slot 18 for adjustably clamping Patented May 9, 1916. r

the blade to the plate. For obtaining thisclamping aninclined boss 19 is formed on the underside of the plate for each dicularly to the inclined surfacesthereof and i through the slotin the blade section, thereby adj ustably clamping the section to the plate.

Suitable lugs 21, 21 project downward from the said plate 6 past the lower end of the blades, and screws 22, 22 in the same plane as the blades are threaded through said lugs so as to engage the lower ends of theblades to hold them against slipping "down in operation, and to obtain a means for forcing said blades up farther through the plate 6 when desired. T

a war he understood that the blades16,

17 are transversel arran ed with res ect tothe plate 6 and that the said plate is suitably apertured as at 23, 23 toadmit the presentation of the cutting edge of the blades immediately above the surface ofthe plate. To prevent these ground edges of the blades from inadvertently coming into contact with the metal bridge 1, I provide a pair of longitudinal beads or tracks 24, 2 1 upon the plate 6 adjacent its side edges which will always retain said plate in spaced relation to the bridge. Furthermore, to prevent the propulsion of the plate 6 farther than necessary a lug 25 at one end and a screw 26' at the other end of the plate are adapted toengage the bridge, the screw being removable inorder to withdraw the plate 6 when desired for cleaning purposes. It will also be noted that I prefertoemploy one blade with a straight edge and one blade with a scalloped or corrugated edge, thissecond-mentioned blade cutting a grooved or corrugated surface in the contents of the hopper and upon the return stroke the straight edged blade cuts the corrugations therefrom, so that neither blade makes an entire slice transversely. Attention is directed at this time to Fig. 3

where one of said blades, viz, the scalloped" blade 16, is there shown projecting through the plate 6, and wherein it can be seen that the blades as I preferably construct them are of a width at least as great as the diameter of the hopper, so that the greatest efficiency is obtained. 7

Into a suitable ear 27 at an upper peripheral point of the" hopper is preferably threaded a stud bolt 28 retained in adjusted position by a lock nut 29 beneath said ear, and pivotally mounted upon this stud bolt to swing in horizontal plane are a pair of arms 30, 30 extending diametrically across the top of the hopper and having ends adapted toenter beneath the opposite flukes 31,31 'ofja double hook 32 integrally formed with said hoppen; vVhen so positioned and held by the hook 32, the said arms 30, 30 form at their middle portions a central threaded sleeve33 in which works a screw 34 arranged upright and centrally of the hopper 5. At the upper extremity of this screw 34 is a suitable actuating means, here shown as a handle 35, and at the lower end of the said screw is carried a follower 36 which preferably fits loose within the hope per. It will be evident that as'the contents of the hopper are cut away, the follower is screwed down to force the remaining contents of the hopper against the cutters, and when the hopper is empty the two arms 30, 30 are swung apart so that it is possible to raise the'screw and follower enbolt between the ear 27 and the arms 30, The arrangement of flukes 31, 31 of the hook 32 is such that after the arms 30 are swung under their ends they can rise upward into the pockets 38 formed by the hook shape of the said flukes, and hence it will be seen that the harder the screw is -operated downward against resistance, the

in a machine of this nature, I employ an annular or arcuate shoulder 39 in connection with each of the gears 8, the said shoulder being of greater radius than a circle through the outer ends of the teethof said gear and also being preferably formed integrally with the said gear. The perpendicular thrust upon the plate 6 is therefore transmitted at the tangential point of contact of the arcuate shoulder 39with said plates, and inasmuch as the said shoulders rotate in unison with the gears, the pres.- sure acting perpendicular to the 'arcuate shoulder creates no relative friction between thesaid shoulder and the plate. To prevent wabbling of the plate 6, segmental portions 40, 40,- of track, preferably formed integral with the legs 1, are placed sufficiently below the plate'6 to provide clearance when the plate is in operation.

Having thus described the invention, what I claim is a v 1. In a machine of the. character described, the combination with a frame having opposite side supports, a hopper mounted on said frame,a cutter plate forming a bottom for said hopper .and adapted to slide between said side supports, saidcutter plate having on its under side series of rack teeth each spaced at a distance from an outer edge of the cutter plate, short segments of track on the inner faces of said side supports. projecting beneath the margins of theslide plate at opposite ends'of:

the same and leaving the middle portion of its length exposed, gears engaging f said racks on the cutter plates andhaving an nular shoulders tangentially engaging the margins of said cutter plate outside said racks between the said, segments oftrack,

a shaft for said gears perpendicular'toaandintersected by the center line of the hopper extended, means, for oscillating saidshaft, and means for feedlng the contents of the hopper'against said cutter plate.

2. In a machine of the character do scribed, the combination of a hopper havmg at an upper circumferential point a pair of inverted hooked fingers the outer ends of which are in spaced relation to the upper edge of said hopper, a pair of arms hinged to the upper, edge of the hopper opposite said hooked fingers and adapted to swing under and be engaged by said fingers, said arms having cooperating screw threaded portions intermediate to their ends forming a socket, a screw adapted to work in said socket, and aifollower in the hopper adapted to be pressed against the contents by said screw.

3. In a machine of the character described, the combination of a hopper hav ing at an upper circumferential point a pair of inverted hooked fingers the outer ends of which are in spaced relation to the upper edge of said hopper, a headed pivot on said edge of the hopper diametrically opposite said hooked fingers, a pair of arms hinged to said pivot and adapted to swing under and be engaged by said fingers, and a spring on said pivot adapted to normally hold said arms upward againstsaid head.
